According to police, the 3-year-old girl, who had no shoes on, walked up to a home in the area of Bimini Drive in Forest Park on Friday morning and knocked on the door. She told the woman inside, "I need my mommy."

Around 12:30 p.m. Friday, police said they had located the girl's parents. Police said she was supposed to have been in the care of a babysitter, who called police around noon when she noticed the child was not in the home.

Brown has serious questions about whether or not that story is true and cried on the phone when Klaus first talked to her. She said the knock was so loud it sounded like a police officer banging on the door.

"That wasn't that baby knocking like that," Brown said. "Somebody deliberately dropped her off and left her there, if you want to hear from my understanding."

She wonders why a babysitter who police said was supposed to watch the girl didn't call police until around lunchtime.

“I feel that, if you’re going to watch somebody’s child, treat them as if they’re your child," Brown said. "But you’re not going to tell me, at 9 o'clock in the morning, you still hadn’t realized that baby was gone.”
